What is the difference between different mesh number
2 min
In the context of bead blasting in CNC services, the terms "80 mesh," "100 mesh," "120 mesh," and "150 mesh" refer to different grit sizes or particle sizes of the blasting media used in the process. The mesh size indicates the number of openings per linear inch in a sieve through which the blasting media passes. Here's a general overview of the differences:
80 Mesh:
Larger particle size.
Removes heavy coatings, rust, and contaminants more aggressively.
Leaves a coarser finish on the material being blasted.
Suitable for applications where surface roughness is acceptable or even desired.
100 Mesh:
Medium particle size.
Balances between aggressiveness and surface finish.
Effective for general-purpose cleaning and preparation.
Provides a compromise between the coarser 80 mesh and the finer options.
120 Mesh:
Smaller particle size.
Removes lighter coatings and contaminants.
Offers a smoother surface finish compared to coarser grits.
Suitable for applications where a finer finish is desired.
150 Mesh:
Fine particle size.
Removes very light coatings and provides a smoother surface.
Ideal for applications where a high-quality, polished finish is required.
Used for precision cleaning and finishing.
The choice of mesh size depends on the specific requirements of the project, including the material being blasted, the desired surface finish, and the level of precision needed. Finer mesh sizes generally result in smoother finishes but may take longer to achieve the desired cleaning or texturing effect. It's essential to consider the material's sensitivity to abrasion and the final aesthetic or functional requirements of the part being processed.

Laser Etching: Complete Technical Guide to Process, Materials, and Industrial Applications
Laser etching is widely used in manufacturing, product design, and industrial marking. However, it is often confused with laser engraving and laser marking, which can lead to incorrect process selection. This guide explains its core principles, process, materials, and industrial applications in a structured way. What Is Laser Etching? Engineering Definition of Laser Etching At its core, laser etching is a process that uses a focused laser beam to alter the surface of a material permanently. Unlike pro......
Anodized Aluminum Colors: Options, Limits, and Real-World Results
Most people treat anodized color like a simple surface finish option in machining, but it doesn’t work that way in real jobs. It’s not merely about choosing a color from a chart and getting the same result every time. In practice, the final color depends on the: Base material Surface preparation Process conditions during anodizing At JLCCNC, we’ve seen the same color callout look slightly different between batches, even when nothing obvious has changed. Small shifts in alloy, oxide thickness, and dye ......
Surface Roughness Measurement: How to Measure It Right
Key Takeaways Surface roughness measurement quantifies the microscopic peaks and valleys on a machined or processed surface using standardized parameters, Ra being the most common, Rz the most useful for understanding extreme deviations. The two main methods for measuring surface roughness are contact measurement using a stylus profilometer and non-contact optical measurement using laser or white light interferometry. How to measure surface roughness correctly involves surface preparation, instrument ......
How to choose between Laser marking and UV printing?
Choosing between laser marking and UV printing for CNC machining service depends on various factors, including the specific requirements of your project. Here are some considerations to help you make an informed decision: (Left: Laser Marking/Right：UV Printing) Material Compatibility: Laser Marking: Works well on a wide range of materials, including metals, plastics, ceramics, and more. It provides high precision and is suitable for detailed markings. UV Printing: Works well on a wide range of materia......
How to Read Surface Roughness Symbols: Drawing Examples & ISO Guide
Key Takeaways Surface roughness symbols define the required finish for individual features on an engineering drawing. ISO 1302 provides the standard symbols used on most international technical drawings. A surface finish callout can include the roughness value, machining requirement, lay direction, and supplementary notes. Ra is the roughness parameter specified most frequently, although Rz is common for some functional surfaces. Correct interpretation of a callout helps match the surface requirement ......
Surface Roughness: Chart, Ra Values, Units & Applications
Key Takeaways Surface finish in machining directly influences how a part seals, slides, fits, and wears during service. Ra is the roughness value most commonly specified on manufacturing drawings. Even the same/similar machining techniques can produce different finishes after changing tooling, cutting data, and material. CNC Milling, CNC turning, grinding, and honing each leave their own surface pattern. A surface roughness chart gives engineers a practical reference during design and process planning......
